Wanna know why I continue to do chisel grind?

Several variations on the chisel grind. Zero bevel, secondary bevel, asymmetric, and Besh Wedge.

As for grip dislodge during a cut, the forces exerted are transferred to the media being cut. Never had an issue with this compromising grip.
 
Just want to chime in that CMFTW is not only a great knife maker he's got the kydex skills to match!

Seriously, not saying anything bad about any of the custom makers I've worked with, all their kydex is more than serviceable but Matt's is a home freaking run, best fitting kydex I've ever owned hands down (yes even competing against kydex benders that just do strictly kydex work and that's it)
 
Here's mine with special country of origin marking!

About 50% of the knives I make are chisel ground.

I honestly haven't found a task that I don't think they are well suited for.

They cut well, and even the "sharpening challenged" seem to be able to put a decent edge on them.

Chisel edges are inherently twice as sharp as a double bevel edge. 15 degrees per side means a double bevel is 30 degrees inclusive, and a single bevel is 15 degrees inclusive like a D/B that is 7 1/2 degrees per side.

When comparing symmetrical and asymmetrical grinds, total bevel angle must be held constant. A chisel grind is no different from a double bevel grind except for the orientation of the total blade angle relative to the handle. A chisel ground blade is like a double bevel that's been rotated a number of degrees equal to that of the per-side grind angle, such that one side of the blade is brought parallel with the central plane of the grip.

Mostly what's impacted by a chisel grind and/or edge is the deflection experienced during the cut for a given hand position and the vector of force.

Mr. FortyTwo,
I read this several times, and I am unsure about something...
Are you describing the back (flat) side of the blade being cut at an angle as compared to the handle?

Something to allow the cutting edge to still center the handle? I am picturing something like a flat ground "V" straight razor.
Thus my confusion... That is not a chisel from my perspective of the definition.
Yes I am confused about this.

Perhaps the back side still flat and, perpendicular to the handle but inset to center the cutting edge?

He's saying that the "included angle" is the angle between the two faces of the blade, regardless of the orientation of that angle to the grip. So one way of looking at a V grind and a chisel grind of the same included angle is as the same edge but twisted in relation to the grip.

Thank you for clarifying that sir.
I was drowning in geometry.

I'll re-read the post.

Edit: Re-read the post, and now it makes sense to me.

Mr. Bang put me right back in the hole...

I have read this several times, and I think that you are saying that I need to double the angle on the bevel side of a chisel sharpened blade which of course would not improve (reduce) the inclusive edge angle, and I would not enjoy the benefit of a very acute (razor like) edge.
I have right and left side chisel sharpened blades. Their included angle is 15 degrees. In use, they behave like scalpels except that it is hard to change direction when cutting. They want go in a straight line. As such, they are great for making uniform slices (sushi, ham, lunch meat, roast beef, etc. A right hand bevel is useful for large cuts where the slices are falling off to the right (I am right handed). A left hand bevel is more useful for small controlled cuts where the lopped pieces are coming toward me (maybe cutting cooked chicken or steak on a plate).
If you want to have a little leeway in changing direction while cutting, choose the double bevel. If you want to go nuts on direction changes while cutting, opt for the convex edge.

I would like to mention that you make an awesome chisel ground blade, your Riptide I grabbed in 2012 is a laser!

I currently have approx 9 active orders on my bench. I've experienced a dramatic uptick in orders since my 1x42 died in July and I started running my 2x72. I'm going to be running a Tormach PCNC770 hopefully by early next year.

Prior to the 1x42 burning out, I maintained a perpetual 2-4 active orders.

I know for a fact that if I offered V grinds, I would become overwhelming popular. Too much for me to deal with.

In the past, my reasons for chisel ground were initially due to my love affair with the Specwar tanto from my teenage years. Then I learned of its push/pull effect in soft tissue resulting in an aggravated wound channel (cool points in my book). Before I knew it, the chisel grind had become as much my signature as the hand carved CMFTW on the flat side of the tang.

So today, it's because this keeps my orders down.

Yo Dawg. I like chisel grinds, ok!?

Can you make my knife say CMFTL?
